6.5 DMA Interrupt Function
The peripheral I/O interrupts of the A/D converters and the serial interfaces, which serve as DMA
trigger factors, are shared with the DMA transfer completion interrupt of the corresponding channel n
(INTDMAn) (n = 0, 1, 4 to 7). When a DMA channel is enabled the specified peripheral I/O interrupt is
no longer applied to the interrupt controller. Instead of it the corresponding DMA transfer completion
interrupt is applied to the appropriate interrupt handler address.
In opposite to the other interrupts serving as DMA trigger factors, the TMR0 interrupts INTTR0OD and
INTTR0CD, and the TMR1 interrupts INTTR1OD and INTTR1CD respectively, are not shared with DMA
transfer completion interrupt of channel 2 (INTDMA2) and channel 3 (INTDMA3) respectively. These
DMA completion interrupts have dedicated entries in the interrupt source list (refer to
”Interrupt/Exception Source List” on page 219
Table 6-4 shows the relations between DMA trigger factors and DMA completion interrupts.

2.
An interrupt request is not generated for a signal, which serves as DMA trigger factor.
Instead of this the defined DMA completion interrupt request is executed on the same inter-
rupt entry address of the DMA trigger factor.
